More stockings were stuffed with Android and iOS devices this Christmas than ever before, according to new data released today. And new device owners spent much of December 25 downloading apps for their new toys.

The analytics firm Flurry said device activations soared from their daily December average of 4 million to 17.4 million on Christmas Day, a 332 percent increase. And it's more than double the 6.8 million devices activated on Christmas last year, the previous single-day record holder. More tablets were activated on Christmas this year than phones. Apple tablets dominated the category, but the Kindle Fire HD 7" made its strongest showing ever.

Meanwhile, app downloads surged, more than doubling their daily December average on Christmas. Device owners downloaded 20 million apps per hour, Flurry says.

Flurry's analytics software is inside more than 260,000 apps, according to the company, which claims to detect 90 percent of all new iOS and Android activations. For a complete look at the numbers, along with some handy charts, check out the company's blog.

Meanwhile, ad firm Chitika released tablet data today showing that Apple devices still generate significantly more Web traffic than their peers, with more than 87 percento of website visits from tablets coming from iPads. But the Kindle Fire has increased 20 percent since last month to 4.25 percent of the market, Chitika said.
